More than a half million miles of pipelines are used to transport natural gas, crude oil, liquid carbon dioxide, refined petroleum products, and an array of other flammable, toxic, or corrosive gases ...
WASHINGTON, D.C. — Gas feeding the flames devouring a San Bruno neighborhood could have been shut off an hour sooner if PG&E had automatic or remotely controlled shutoff valves on the pipeline that ...
The committee will study current and potential methodologies and standards, including regulatory criteria, for deciding when an automatic shutoff valve, remote controlled valve or other equivalent ...
Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...
A Dec. 11, 2012, natural gas pipeline explosion in Sissonville, W.Va., shows that work still needs to be done to inspect older lines, install automatic or remotely operated shutoff valves, and improve ...
Engineers at Moog have developed a line of explosion-proof (ATEX-certified) flow and flow/pressure control valves that handle from 19.8 gpm to 951 gpm and carry IP66 protection. The valves feature hot ...
Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
Microfluidic technology has developed greatly in recent years, enabling multiple analysis systems to be placed on a microfluidic chip. However, microfluidic large-scale integration of control elements ...
